Patent GB-737889-A (GB)
Title: Treatment of ores or slags for the recovery of vanadium
Inventor: REEVE LEWIS
IPC: C22B34/22
Filed: 1952-10-20
Abstract: Vanadium is recovered from iron ore or slag by converting the iron and the vanadium into volatilizable chlorides with hydrochloric acid and separating the vanadium chloride from all or some of the iron chloride by or after distillation in the presence of hydrochloric acid.  The ore or slag is preferably treated in a fluidized state with hydrogen chloride gas, as described in Specification 677,690, suitable temperatures being 150 DEG  C. in the case of ore and 600-850 DEG  C. in the case of slag. The distilled vapours may be condensed in two stages, the first at 150-180 DEG  C. yielding dry iron chloride together with manganese chloride if present, and the second yielding an aqueous acidic solution of vanadium chloride; which may be evaporated or roasted to give vanadium pentoxide. Alternatively the distillate is condensed in one stage to yield an aqueous acidic solution of the mixed chlorides which on evaporation to dryness is converted into oxides.  These may be separated by reconversion to chlorides and redistillation, or the mixture may be used as such for making ferro-vanadium.  Alternatively the iron may be separated by treating the mixed chloride solution with an organic solvent, leaving vanadium and manganese which may be separated by redistillation.  Specifications 677,645, 677,691 and 677,904 also are referred to.

Patent GB-694975-A (GB)
Title: Improvements in processes for the simultaneous production of yeast and spirit
IPC: C12P7/06
Filed: 1950-10-31
Abstract: In a process for the simultaneous production of yeast and spirit by fermentation, the fermentation is first carried out under conditions hindering the growth of the yeast which leads to a higher concentration of alcohol in the fermentation liquor, the alcohol formed is separated from the yeast, the conditions hindering the growth of the yeast are continued until a temporary decrease of the yeast growth occurs which is then followed by an acceleration of the yeast growth by changing to the usual fermentation conditions.  The hindering conditions which can be used separately or in combination are: (a) use of the substrate in such a concentration that a higher alcohol content occurs in the ferment during fermentation, (b) use in higher concentration of substrates poor in or free from growth promoting and activating substances, (c) limitation of the oxygen addition.  The conditions hindering the growth of the yeast and leading to a temporary decrease of the yeast growth includes the following either singly or combination: (a) use of substrates which are hard to ferment or reduced quantities of substrate, (b) use of substrates which are poor in or free from growth promoting and activating substance, (c) limitation of the addition of inorganic nitrogen compounds, (d) the interruption of the addition of inorganic nitrogen compounds, (e) employment of abnormally low temperatures of about 10-22 DEG  C.  The yeast used in the process may be cultured under normal conditions or with over feeding and its fermentation and multiplication properties may have already been temporarily reduced at the begining of the culture.  Examples are given.
